This study is designed to compare the Thopaz chest tube drainage system to the traditional collection chamber system. The Thopaz system is already in clinical use in the United States and throughout the world. As such, this study is not evaluating safety or efficacy of this system both of which have already been demonstrated. This study's primary aim is to determine whether the use of a digital chest drainage system compared with a traditional system affects duration of chest drainage and length of hospital stay.
